Descriptions

The Comcast firmware on Cisco DPC3939 (firmware version dpc3939-P20-18-v303r20421746-170221a-CMCST) devices allows remote attackers to execute arbitrary commands as root by leveraging local network access and connecting to the syseventd server, as demonstrated by copying configuration data into a readable filesystem.

El firmware de Comcast en los dispositivos Cisco DPC3939 (versión de firmware dpc3939-P20-18-v303r20421746-170221a-CMCST), permite a los atacantes remotos ejecutar comandos arbitrarios como root mediante el aprovechamiento del acceso a la red local y conectándose al servidor syseventd, como es demostrado por el copiado de los datos de configuración en un sistema de archivos legible.
